Analyzing Iran’s Local and Regional Droughts Using the Theory of Runs and Standardized Precipitation Index (SPI)
The primary objective of the present study is the investigation of the various properties of Iran’s local and regional droughts based on the theory of runs and standardized precipitation index (SPI). Thus, in order to accomplish this goal, the annual precipitation data of 63 synoptic stations were procured from Iran’s meteorological organization for a 30-year period (1986-2015).. First, based o...
متن کاملSpatiotemporal Variation of Precipitation Regime in China from 1961 to 2014 from the Standardized Precipitation Index
Prediction of drought and flood events can be difficult, but the standardized precipitation index (SPI) calculated from monthly data may be a useful tool for predicting future dryness/wetness events in China. The rainy season SPI was calculated from monthly precipitation data from 3804 meteorological stations in China. The spatiotemporal variation, periodic change, and trend in rainy season SPI...
متن کاملExtreme value theory for precipitation: sensitivity analysis for climate change
Extreme value theory for the maximum of a time series of daily precipitation amount is described. A chain-dependent process is assumed as a stochastic model for daily precipitation, with the intensity distribution being the gamma. To examine how the eective return period for extreme high precipitation amounts would change as the parameters of the chain-dependent process change (i.e., probabili...
متن کاملZoning Droughts By Standardized Precipitation Index in Esfahan Province (Iran)
The Standardized Precipitation Index (SPI) has become a popular measure of drought across the globe. In this study, Standardized Precipitation Index (SPI) was used in annual period of time to survey on drought. Also, in order to zonation frequency of drought, geographic information system (GIS) software and Kriging method used for extracting dry areas. The zoning maps show most severe drought i...
